The Medicina VLBI antenna participated in the EUR137 experiment carried out in September 2015 using, as reference systems, both the local H-maser and a remote H-maser hosted at the INRIM labs in Turin, separated by about 550 km. In order to assess the quality of the remote clock, the observed radio sources were split into two sets, using either the local or the remote H-maser. A system to switch automatically between the two references was integrated into the antenna field system. The observations were correlated in Bonn and preliminary results are encouraging since fringes were detected with both time references along the full 24 hours of the session. The experimental set-up, the results, and the perspectives for future radio astronomical and geodetic experiments are presented. | Titolo del convegno: | 9th International VLBI Service for Geodesy and Astrometry (IVS 2016) General Meeting "New Horizons with VGOS" | Luogo del convegno: | Johannesburg, South Africa | Periodo del convegno: | March 13-17, 2016 | URI: | http://hdl.handle.net/20.500.12386/24288 | URL: | https://ivscc.gsfc.nasa.gov/publications/gm2016/ https://ivscc.gsfc.nasa.gov/publications/gm2016/034_perini_etal.pdf |
